NASA chooses an ancient crater as the next landing site for Mars

The Jerez crater, located 28 km (45 km), was chosen as a mission destination, due to begin in 2020, due to its potential for scientific research.

"The target location in the Crater Isero offers a geologically rich terrain, with a land form that reaches another 3.6 billion years, potentially able to respond to important issues in planetary evolution and astrobiology," said Thomas Zurbuchen, assistant administrator of the Scientific Mission of NASA.

"Obtaining samples from this unique area will revolutionize the way we think about Mars and its ability to preserve our lives," he added.

The crater was selected after a five-year search that examined about 60 other locations on Mars.

The ancient lake-delta system of Jezero offers promising targets for sampling at least five rock types, including clays and carbonates, which have great potential to preserve the signatures of the past life, NASA reported in a press release posted online.

The material that is transferred to the large-basin delta can also contain a wide range of minerals from inside and outside the crater, he added.

Organic matter has already been found on the planet in soil samples taken from three billion years old mud and methane is detected in the atmosphere of Mars.

Landing on Mars is incredibly difficult. Only 40% of the missions sent to the Red Planet by any agency are successful.

Part of this is due to the narrow Martian atmosphere, which is only 1% of the Earth, so there is nothing to slow down something that is trying to land on the surface.

The United States is the only country to have missions that survived the landing on Mars. NASA is passing through the past, orbiting the orbit, landing and launching over Mars from 1965.

"Once out of reach, you can now"

The geological diversity that makes the Crater of the Lake is interesting for scientists also makes it challenging to enter, descend, and land the rover.

NASA, as well as its impacts on the Delta River and a small crater, contains a number of rocks and rocks in the east, cliffs to the west, and depressions filled with Eolian forms of a ship (windshield waves that can engulf a rover) several locations.

"The Mars community long wished for the scientific value of sites such as Crater Jezero, and the previous mission was planned to go there, but safe landing challenges were considered too high," says Ken Farley, a Mars Science 2020 project scientist at the Laboratory for a NASA airplane laboratory in Pasadena, California.

"But what once was out of reach is now possible, thanks to the engineering team 2020 and progress in technology for entry, descent and landing on Mars."

When the landing site began, the mission engineers had already mastered the landing system so that they could reduce the Mars 2020 landing zone to 50 percent less than the landing of NASA's Curiosity King Gale in 2012 .

Sky crane

NASA has added a new capability called "Relative Ground Navigation", which will allow the launch of the "sky crane," a rocket propulsion system carrying the rover to the surface to avoid dangerous areas.

"Nothing was more difficult in robotic planetary research than Mars landing," Zurbuchen said.

"The Mars 2020 engineering team has done a tremendous job to prepare us for this decision. The team will continue to work to truly understand the TIR system and the risks involved, and we will look at the findings independently to ensure that they we maximized our chances for success. "

On November 26, NASA's Mars Insight strip will touch the Red Planet at 3 o'clock. EST, for the first time in six years a new mission will land on Mars.

Insight, or Internal Research using seismic research, geodesy, and heat transport, will consider a part of Mars that we know at least for: the deep inside. It started on 5 May.
